Just FYI. I signed up for the
Castaway Cay Jet Ski excursion several times over the years. Not once did we actually get to go out due to wind/weather. If I recall, the time periods were between late-February and May. It was disappointing each time. However, one year
Royal Caribbean did send us out on a jet ski excursion during a very choppy, windy period, and it was miserable. In retrospect, I think Disney made the right call.
